. COOLING RADIATOR.

Application filed December 17, 1923. Serial No. 881,159.

To all whom it may cor-cm:

Be it known that I, VViLLIAM A. ODEN- DAHL, a citizen of the UnitedStates of America, and resident of the city and county of Denver,Colorado, have invented a new and useful Cooling Radiator, of which thefollowing is a specification.

' An object of this invention is to provlde an improved construction forcooling radiators adapted for useon automobiles for the purpose ofcooling liquid employed to prevent overheating of a gasoline motor .usedto drive the same.

A further object of this invention is to provide improved .means forfacilitating assembling, dismounting, separation and repair of the partsof a cooling radiator.

A further object of this invention is to provide an improvedconstruction. for several of the parts of a cooling radiator;

My invention consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out v in the claims andillustrated by the accompanying drawing, in which- Figure 1 is a frontelevation and Flgure 2 a side elevation of a radiator embodying myimprovements, the shell being omitted. Figure 3 is ahorizontal section,on an enlarged scale, on the indicated line 3-3 of Figure 1. Figure 4 isa detail perspective illustrating one form of construction and arranement of end bars, fins and struts employed in the device. Figure 5 is avertical section through a part ofthe radiator core furtherillustrating-the structure shown in ,Figure 4.

- Figure 6 is a'detail perspective showing a modified construction for.the fins, whereby. .a part of each fin constitutes a strut or sup-. portfor a superposed fin.

Figures? and 8 are vertical sections and plan respectively illustratingvarious forms of connecting radiator tubes to a tank 'In theconstructionof the radiator as shown the-numeral 10 designates a bottomtank, 11 anupper tank, 12 each of a series of vertical tubes connecting,communicating with and spacing apart the tanks 10 and 11,

'13 an outlet pipe for the bottom tank andlt an inlet pipe for the uppertank; said upper tank also being prov-idedwlth a filling nipple 15 atthe center of its top. In a general way the tanks and tubes areconstructed in a common and well known manner and are Y holes.

not involved in this invention except as a foundation for the otherelements and as hereinafter described. In Figures 7 and 8 a tank header16 is shown formed with holes therethrough adapted to receive one endeach of tubes 12. The holes in the header are reamed out and tapped atone end and glands 18, 19, 20, or various forms, are mounted loosely onthe several tubes and are adapted to be screwed into the tapped portionsof the holes in the header and, at their inner ends engage gaskets 21and seal the joints between the tubes and header. The gland 18 is formedwith a tapered inner end opposed to atapered bottom of the reamed outportion of the appertaining hole and the gasket 21 therein is locatedbetween saidtapered end and bottom. The gland 18 also is otherwisecylindrical and is formed with notches 22 in its outer end adapted to beengaged by a spanner for operation of the gland, either for seating orunseating thereof. ,The tapered end of the gland l8 and tapered bottomopposed thereto are sphere-shaped.

The gland 19 is formed with a .frustum shaped inner end opposed to afrustum shaped bottom of the reamed out portion of the appertaining holein the header and the gasket 21 therein is located between said end and.bottom. The gland 19 also is formed with a nut 23 on its outer endadapted to'be engaged by a wrench for op- I eration of the gland, eitherfor seating or unseating thereof. The gland 20 is formed with a fiatinner end opposed to a flat bottom ofthe reamed out portion of theappertaining hole in the header and the gasket 21 therein is locatedbetween said end and bottom. The gland 20 also is formed with a nut .23on its outer end adapted to be engaged by a wrench for operation of thegland, either for seating or unseating thereof. The header 16 mayconstitute the top of the tank 10 or the bottom of the tank 11, and isof material and considerable thickness to accommodate the reamed andtapped The gaskets 21, under compression of the glands, provide andmaintaln frictional engagement with the tubes. 12 sufiicient to keepsaid tubes in proper relation with the tanks, thus providing means forconveniently assembling, or removing any tube for repair orsubstitution.

The 'core of the radiator is built up and filled in of two sets orseries of fins 24, 25,

all of which fins are alike in form and construction and areinterchangeably usable. Each set or series of fins24, 25 is connectedwith and carried by end bars 26, 27 and 28, 29, two for each set orseries, and said end bars are of like form and construction, except asto fastening means, and are-substantially interchangeably usable. Theend bars are adapted to be mounted in pairs between end portions of thetanks 10, 11 as shown. -The fins 24, 25, are each formed of thin sheetmetal with a fold or roll 30, on its outermost long margin and is formedwith outwardly-opening notches 31, extending thru the fold or roll andof a width corre sponding to the thickness of and adapted to receive theend bars 26, 27, 28, 29 respectively. The notches 31 extend throughoutsomewhat more than half the width of each fin. The end bars 26, 27, 28and 29 are formed with inwardly-opening notches 32, one for each fin ofthe respective series, and said notches extend throughout substantiallyhalf the width of the bars and are adapted to receive those portionsoithe fins at the inner ends of the notches 31. Thus the fins Y and endbars are halved together for assembling in sets and they may beconnected by culation of air between the tubes and between and throughthe fins adjacent to the tubes when the fins are assembled as shown inFigure 3. These notches 34, 35 also permit the sets of fins to bewithdrawn from the tubes by lateral manual movement of theend bars.Struts, spacers or supports 36, 37 are formed of thin sheet metal withfolds or rolls 38 on their inner margins and said struts are formed withoutwardly-opening notches 39, 40 adapted to receive portions ofthefins24, 25, said fins, in turn, being formed with inwardly-opei'iingnotches 41, 42 adapted to receive those portions of the struts at theinner ends of the notches 39, 40. The struts are arranged verticallybetween transverse rows of the tubes 12 and frictionally engage thefins, or they may be secured to the fins by drops ofsolder 43, so thatsaids'truts may be removed and replaced with the sets or series of finsin lateral manual movement of the end bars. Apertured ears 44, 45 arefixed to the outer surface of inner marginal portions of the end bars26, 27, 28 and 29, in sets near the upper and lower ends of said bars,and when the parts are assembled as shown said ears register verticallyon opposite sides of the radiator and are connected in sets by pins 46adapted for manual removal and replacement. The interengaging pins andcars provide convenient means of connecting the end bars in pairs onopposite sides of the radiator and through said end bars, for connectingthe sets of fins and struts on opposite sides of the median line of theradiator.

li'pon removing all the pins 46, theend bars, tins and struts may beremoved forwardly and rearwardly from the tubes 12, which done accessishad to any tube for the repair, removal or replacement thereof, Or,under the same conditions, any strut or fin may be removed or repaired.

After any repair or renewal is made the sets of series of end bars, finsand stints may be replaced relative to the tubes 12 and reconnected bythe pins 46 in intimate and stable relation to the tubes. \Vhenassembled as shown, the struts support the interior portions of the finsin proper spaced relation, and said struts and fins divide the air,forced by tan not shown, in passing througii the radiator and about thetubes, also permitting the air to circulate freely up and down andaround the tubes, thus applying the cooling air intimately and freely tothe tubes. In Figure 5 both the fins 24, and struts 36, 37 are showncontacting on the median line of the radiator.

In Figure 6, the struts as separate entities are omitted, and the fins24, 25 are formed with recurved-integral lugs 36, 37' extending upwardlytherefrom in the locations otherwise occupied by the struts. The lugs oneach fin engage and support the fin above it, and said lugs havesubstantially the same function as the struts in supporting, spacing andbracing the'fins and in operating with said fins to divide the airpassing through the radiator.
